I dropped a K&N "Air Charger" CAI into my 2011 Toyota Tacoma...
Here is my god honest review...
Well the intake took about 60-70 Minutes to completely install. Every bolt lined up and everything fit like it was supposed to, nothing stretching to fit, nothing off. This was quite possibly the smoothest install i have performed on any truck in while.
I took the stock intake out and built the K&N to test weight difference, like expected the K&N was about half the weight and 50% more space efficient.
the K&N heat shield seemed to make a good seal and isolate the filter from the engine.... except the huge hole that the tube goes through... that being said, it probably isnt the most efficient heat shield in the world.
my oxygen sensor fit right in, all the tubes lined up and fit perfect and it clamped to the throttle body just like it should.
so enough on fit and looks, what about performance?
well i drove 4 full tanks with K&N recording distance on two and performance on 1, and the very first tank was to let the computer adjust.
since i dont have a dyno to accurately test the K&N i relied on my trusty Butt dyno... i know my truck better than anyone else and i think it should be about 75% accuracy of what a dyno will read...
well the K&N didnt exactly specify the gain i should look for, but in my real world situation it seemed to only gain 2-3 MPG (circumstantial)
i wouldnt say its the K&N that helped.. maybe it did maybe it didnt... could just be the way i was driving and weather etc..
Well lets be honest here... the k7n claimed 13-15 hp was pretty off... i would say about 5-6 hp gain.. but any poney gain is a friend of mine..
the k&n really helped in the top end power around 4-6k rpm's
with none of the gain below 3k rpm
Wow... this thing sound amazing.. anything above 4k rpm is like my trucks engine came alive and wants to eat the next door neighbors dog.. it really growls and howls and i am impressed as sound goes
MPG gain?- not really
HP gain- maybe 5-6hp gain
Seem to allow more air flow?- yes it seems to be alot more flowing
Would i recommend?- i would definitely recommend it but dont expect the 13-15hp claim
Thank you for reading
speed limit was 45 mphs, i will admit i was doing 50-55
